How to run a thread after every 25min in jmeter

I am hitting a rest API using HTTP GET request that contains authentication token in header. So in a thread group i am hitting authentication server to get authentication token. In the subsequent thread groups i am going for HTTP GET request

TEST plan (property auth)
  ThreadGroup(authentication)
    http GET to get authentication token
    extracting response and putting in auth
  
  Thread group(GET)
    http GET
    
  Thread group(GET)
    http GET
    
  and soo on
  

Here the authentication token will expire for every 25 min so i need a mechanism to generate authentication token for every 25 min with out interrupting the work of on going HTTP GET calls
